Thanks for the links. Im awaiting the approval from the website. It seems that I did go a bit overboard with the exhaust. I also need to advance the timing of the transfer ports. I think I might do that tonight. I would like to turn the case down for more compression, but I dont have a lathe. I do have plenty of power for the project I am going to do, but more never hurt anyone....
If I get the mods done, I might get to run the engine tomorrow. there will be a video, if performance is increased.
One thing I dont really get, is why this thing is a dog with the 16-8. It should have improved. The more I think of it, the more it frustrates me. I dont think I can fit a 16" prop on the plane im going to build, but I would be happy if I could get 7500 or better with the 16-8.

Is there a big difference between the poulans with the bolt on mufflers and the ones with the springs?
